I resubbed to World of Warcraft today to play Classic, however when I try to launch the game I get a popup that said “Your 3d accelerator card is not supported by World of Warcraft. Please install a 3D accelerator card with dual-TMU suport.” This popup only appears when I try to launch World of Warcraft Classic. When I launch World of Warcraft Shadowlands, the game launches normally and I am able to login and play.
Things I have tried already:
Updated Nvidia Graphics Drivers.
Used Display Driver Uninstaller to remove drivers completely and reinstall.
Updated power settings to High Performance Mode.
Changed Nvidia Control Panel settings to High Performance Mode where applicable and selected Nvidia GTX 980 where applicable.
Ran File Check Scan through Blizzard Launcher and it didn’t say anything when complete.
Uninstalled World of Warcraft Classic and reinstalled.
Reset World of Warcraft Classic settings to default from Blizzard Launcher options.
Went into World of Warcraft Classic.exe properties and disabled full screen optimization and checked run as administrator.
This is the digital library scanner they include. If you disabled that before running this test, please reboot, try opening WoW Classic again, and then run a new DxDiag.
Here is a current DXDIAG report, after disabling the Game Manager Service, restarting my PC, and then trying to open Classic WoW again. It looks like it still says the same thing to me but I could be reading it wrong, I’m not very familiar with how to read a DXDIAG.
I was looking at this thread late last night. It’s a puzzle. You have already completed some good troubleshooting steps. Let’s try disabling some processes on the machine - then test.
Thanks for being willing to help with my issue! I tried what was listed in that article. I disabled every single startup program, rebooted my PC, tried to launch WoW Classic, and unfortunately got the same popup again.
Here’s the DXDIAG report from after I did all that:
Hmm. Even if the game was somehow detecting your Intel 530 onboard that is supported in Classic. This is curious - my usual Blizzard Tech contact is on days off so I can’t run this by them.
You mentioned you reinstalled Classic. Let’s clear some Battle.net folders.
First restart computer to end any running Blizzard processes. Then right-click the Start button and select Run to open the Run command in Windows.
(or use keyboard shortcut: Windows key + R)
Type or paste %PROGRAMDATA% in the Run command box. Click OK. The ProgramData folder should open. Delete the Battle.net and Blizzard Entertainment folders.
Afterwards right click on the Battle.net desktop icon. Select “Run as Administrator”.
Just going to Run something by you, if I remember correctly WOW Vanilla on a Multi Monitor setup always picks Monitor “0” When on an Nvidia card. Monitor zero will always be the DVI port if you have something plugged into there. Which I see from your DXdiag is plugged in. If you are running the displays so that the one plugged into HDMI is primary and the one on DVI is secondary in windows, you could have a potential issue.
I owned this card for a bit, I distinctly remember being frustrated that I couldn’t 3d game on one of the ports due to the cards hardware limitations. I had to switch my displays around so that 3d rendering happened on the “Main display” (set in windows or Nvidia control panel) since that version of wow wanted to be on a specific port on the GPU. That caused the client not to start. In the End I didn’t want to run 3d games on that monitor (My new monitor was/is DP and HDMI only) so I chucked the second display and went single.
Try unplugging the Monitor on the DVI port if it’s not your main, or just try one monitor. I used to own that card and a 960, I remember having a limitation which monitor was actually set to main in windows for gaming. Two issues I remember the most were it stayed in full power state when running multiple monitors (So it would never clock back down), and it would only game on the monitor that is “0” (Zero) on the physical card. if something is in the DVI port that is always zero. If whatever display is connected to the DVI port IS NOT, display ZERO or “Main display” in windows, wow would not start.
Again I am just vaguely remembering this, years ago, lol. I think this is how my beautiful samsung monitor ended up in my garage plugged into my file server. I think the only way to get wow not to throw an error while starting was to go out and buy to displayport to HDMI cables and back then they were like $50 to $75 a pop, I was like nah, I can just have my laptop on the side. lol.
TL;DR wow (that version) wants to run on a specific monitor.
SIde note, if you are running Discord, try disabling in game overlay. That could be the issue with some pre “GPU accelerated hardware scheduling” Cards. WHich your card falls under. (Maxwell series cards) Geforce also has an overlay that is on by default. Steam too.
Here is another forum post with the same issue.
The archives don’t go back far enough for when in posted unfortunately. I remember posting a solution too.
I tried what you said, deleted the Battle.net and Blizzard Entertainment folders and then ran my Battle.net as admin. It had me install WoW Classic again but it was super quick to install so it must not have been fully uninstalled or anything. Tried launching once I was able and got the same popup.
I’m thinking I might try a full uninstall of all Blizzard products and reinstall clean and see what happens. I saw another thread where a guy was having all the same issues as me and nothing was working for him either and the full reinstall is what did it. I’ll report back.
EDIT: THE FULL UNINSTALL/REINSTALL WORKED!! Thank you all so much for troubleshooting this with me.
Good to see Lunaeriss - I still have no idea what was going on there. It might be something along the lines of what Aalliyah posted then the game reinstall sorted it out.
